While the pros are recovering from Friday night parties, why don't you tell us more about your current floor. What kind of joist support do you have (you can play with the deflecto in the blue bar at the top of the page), how thick is your subfloor and how many layers? Natural stone is very picky about its substrate. It likes a very stable structure and several layers of plywood.
